About this RO System?

Known as Whirlpool UltraEase by its commercial name – is a reverse osmosis water filtration system developed by Whirlpool.

Whirlpool RO water filter common setup

It aims to deliver bottled water quality at your kitchen sink by reducing the most common contaminants found in municipal drinking water or private well supplies.

The under-sink filter is characterized by a very compact footprint and a simple installation, and it even comes with its own faucet for quick, fuss-free use.


Contaminants Removed by this RO System

Through its 3-stage filtration, it can remove a wide range of contaminants, including sediment, dissolved solids, as well as most chemicals.

It also successfully removes chlorine and fluoride. This two (2) chemicals are added to the municipal water for disinfection.

Like most reverse osmosis filters, this UltraEase model can also remove lead and arsenic, as well as microbial cysts.

A lack of UV light limits its antibacterial properties, but overall, you can expect to drink purer, healthier, better-tasting water.

Very Important Note

This RO filtration system was not designed to treat water that could be potentially be micro-biologically contaminated. If you do need to do it, then get a system that includes UV treatment. Please see our RO Water filter section to find a few alternatives.


How to Setup, Operation and Maintenance the Wharos5

  • Setup

This Whirlpool reverse osmosis system is easy to install either by handy homeowners or a plumber. Due to its compact dimensions, it occupies a really little space under that sink, and it’s a great choice for a small apartment or studio.

Wharos5 Suggested Setup

A thing we truly like is that it comes with almost everything needed for a fuss-free setup. While some fittings may not be included in the package, you can find all additional parts at most home department stores.

As you could expect, the area needs little to no preparation. Just turn off the hot and cold water valves to prevent accidents, then install the filter on the cold water supply pipe and connect it to a drain. The system comes with a storage tank and faucet, which are also easy to setup.

Comprehensive instructions make this step easy, so you can leave the guesswork out of the game and get the installation right quickly and easily.

  • Operation

Once installed, the Whirlpool reverse osmosis Wharos5 is very easy to operate. Just turn on the system’s faucet to get clean, fresh drinking water.

While the system utilizes cold water from your main supply, it also allows you to keep two water lines. In other words, you can use filtered water for drinking or washing vegetables, or unfiltered water for doing dishes.

A thing to keep in mind is that the system has a lower pressure than the water pressure provided by the main faucet. Luckily, the storage tank can keep sufficient drinking water for fast glass filling whenever you’re thirsty.

Lastly, we advice you check the conditions of the included battery that powers the LED indicator; the last thing you want to happen is having a faulty battery.

  • Maintenance

Like all reverse osmosis systems, this one requires periodical maintenance. Depending on the pH level of the water in your area, the filter cartridge should be replaced every 6 to 12 months (for the pre and post filter).

Typically, the higher the pH level, the more frequently you’ll have to replace the filters.

For the membrane filter, the manufacturer recommends to replace it between one (1) to three (3) years. I think this is quite a range so keep an eye on the quality of your final water.

WHEERF and WHEERM Filters

High levels of chlorine may also damage the filters faster than water with lower levels of the chemical.

The replacement filters are readily available on the manufacturer’s website. To change them, all you have to do is follow the simple steps in the system’s instructions booklet.

We recommend you test you water before the first time of using the water filter and every 1 year for verification.

Filters apart, you will also have to change the LED battery when drained. The operation is as simple as it gets; all you have to do is unscrew the right side of the faucet base to access the battery compartment and replace it with a compatible CR2032 battery.

The system also comes with a troubleshooting cheat sheet you can use to solve most issues.

Important Facts

  1. System sanitation: Before the first use, it is important to sanitize the filtration system. If you ended up buying the Wharos5 RO filtration system, you can use the included eyedropper to inject bleach (5.25%; that is 3 ml). This is enough to eliminate any foreign material going into the system during the installation.
  2. Purging the system: once the bleach has gone through the system, it is important you purge it. The manufacturer recommends to run it for approx 24hr before you drink the first glass of water.

Downsides

While it is fantastic considering its price point, it comes with some downsides too.

Perhaps the greatest is the rather scarce quality of the faucet. Sure, you can easily replace it with a better quality one, but you should still know that the one it comes with is rather cheaply made.

We think the system has limited treatment capabilities compared to other RO system in the market. You should be testing your water supply quality periodically to avoid issue with other contaminants.

Apart from these small annoyances, the Wharos5 brings true value for money and is undoubtedly a great reverse osmosis system for most homes.


Whirlpool Wharos5 Review Final Thoughts

This Whirlpool UltraEase RO water filter is one of the best home reverse osmosis water filters. It comes at an affordable price point; it can remove most contaminants from municipal or well water, easy to install and requires little maintenance.

Despite of many positive aspects, it has some limitations, but as long as you have tested your water, this is a great option for getting clean, tasty drinking water.

Helping you save a lot of money by ditching bottled water, the Whirlpool Wharos5 reverse osmosis system is surely worthy of your attention.
